MANTLE-SUPPORT FOR GAS-BURNERS.

SPECIFICATION forming part of Letters Patent No. 731,961, dated June 23,1903.

Application filed November 14, 1902. Serial No- 131,377. (No model.)

To all whom it may concern:

Be it known that I, HILMAR J. SIEGEL, a citizen of the United States,residing at Monaca, in the county of Beaver and State of Pennsylvania,have invent-ed certain new and useful Improvements in Mantle-Supportsfor Gas-Burners; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention has relation to gas-burners of the XVelsbach type, and hasfor its object the provision of novel means for supporting the mantlewhich is supported above the burner and heated to incandescencc by thegas from the burner.

Heretofore it has been customary to support the mantle by suspending itfrom the hooked end of a wire, which was attached to the burner at 'itslower end and extended above the top of the mantle outside of the same.These wire supports being subjected to the intense heat of the gasfrequently become so soft as to bend, and as the mantles are exceedinglyfragile the bending of the wire results in the destruction of themantle. Another objection to the .use of the wire supports is that beingvery, light and springy they vibrate under any shock that may becommunicated to the gas-fixture and bysuch vibration destroy the mantle.It has also been proposed to support the mantle upon a rod of magnesia;but such material is not well adapted for the purpose owing to itsliability to break off under the action of the heat.

I have discovered that certain natural products are well adapted for useas supportingrods for mantles, among these being slate and kindredstones, which are easily worked into the desired shape, are notappreciably affected by heat, and are of such strength that even in theform of a slender rod they will support the mantle without any danger ofbreaking or of injuring the mantle by vibrating under shock communicatedto the fixture on which the mantle is supported.

My invention consists in the novel material and construction,combination, and arrangement of parts hereinafter described and claimed.

Referring to the accompanying drawings, Figure 1 is a vertical sectionalview of a burner of the Welsbach type with my improved mantle-support.Fig. 2 is a detail View of the supporting-rod, and Fig. 3 an end view ofthe same.

-A designates a gas-burner of the type usually employed in connectionwith incandescent gas-lights, and B designates the wovenwire screen atthe top of the burner. A metallic thimble O is fixed at the center ofthe screen B, and said thimble serves as a socket for a rod D, of slate,which is of a length sufficient to extend to the top of the mantle E.The rod D is formed with a shoulder (Z, and a ring or washer F, whichhas projecting points ff, rests on the shoulder (Z and supports themantle, fitting within the neck of the same, the spaces between thepoints f f allowing the products of combustion to escape from within themantle.

The device as above described provides a simple, inexpensive, andefficient support for the mantle, and the slate of which the rod iscomposed being unaffected by the heat is practically everlasting and byits strength and rigidity obviate the danger of the mantle being brokenby accidental blows against the gas-fixture to which the burner isattached.

The rod D may be provided with a notch 61, as shown in the drawings, andwhere the rod is to be used in connection with mantles which have a loopor cross-piece of asbestos cord across the neck the mantle can be hungupon the rod by resting the loop in the notch and the washer F dispensedwith.

Having described my invention, I claim 1. A support for incandescentmantles, consistin g of a slender rod of roof-slate, and said rod beingformed with a notch on its upper end to receive the cord of amantle,-substantially as described.

2. A supporting device for incandescent mantles consisting of a rod ofslate having a shoulder near its upper end and a metallic washer resting011 said shoulder.

A supporting-rod for incandescent mantles consisting of arod of slatehavinganotch on its end to receive a loop 011 the mantle, a shoulderbelow said notch and a washer resting 011 said shoulder.

I11 testimony whereof I have affixedmy signature in presence of twowitnesses.
